Staff DevEx Engineer at Replit, focusing on improving developer velocity and tooling for a platform that uses AI to generate over 60% of merged PRs. The role involves maintaining codebases, optimizing build/test pipelines, driving code generation, setting code quality standards, and partnering with the AI team to enhance the internal AI platform and its strategy.

What you'd actually do

  1. Maintain and evolve our codebase structure — a complex TypeScript monorepo, Go services, npm packages, and internal Agentic tooling.
  2. Own the build and test pipelines and optimize them to minimize build times and improve developer iteration speed.
  3. Drive code generation and type-safe interfaces across service boundaries (e.g., GraphQL, Protocol Buffers, gRPC, OpenAPI).
  4. Set the standards for code quality using automation tools such as TypeScript, ESLint, Prettier, and Go linters/formatters — building custom rules and plugins to enforce Replit-specific requirements.
  5. Partner with the AI team on our internal AI platform (which generates >60% of all merged PRs at Replit) to improve the Agent's output and shape strategy around its default stack.
